gcc 8 & 9 appear to be more picky with regards access alignment to
packed structures, leading to this warning in dns.c:
dns.c:261:2: error: converting a packed ‘struct dns_question’ pointer
(alignment 1) to a ‘uint16_t’ {aka ‘short unsigned int’} pointer
(alignment 2) may result in an unaligned pointer value
[-Werror=address-of-packed-member]
261 | uint16_t *swap = (uint16_t *) q;
Work around what I think is a false positive by turning the warning off.
Not ideal, but not quite as not ideal as build failure.
